Hybrid Solar Biofuel Cells

CTCN Keyword Matches:

Current biofuel cells have major limitations as they often suffer from poor electron transfer efficiency and insufficient power output. Researchers from the School of Chemistry have developed a hybrid biofeul cell which uses light absorbing molecules on nanostructured interfaces to create a hybrid device which can overcome these limitations. The present technology includes a nano-structured electrode surface to which light absorbing dyes and redox proteins have been attached. Solar radiation can improve the efficiency of the protein’s communication with electrodes and allows for greater power output from the hybrid cell.


• Improved electron transfer efficiency and power output • Can lead to more efficient biosensors and other devices
